1 Claim.

tachable handle adapted to accommodate a variety of tools.

The object of this invention is to provide novel and facile means givingdetachability between the tool and its handle. By means of thisinvention a single handle of convenient form is provided for a pluralityof tools so that economy of cost and space is obtained, the combinationbeing efficient and the detaching means being facile and certain.

While the invention is defined in the appended claim, the followingdetailed description, taken with the accompanying drawing, disclose apreferred embodiment of the invention with some suggested modifications.

Fig. 1 is a top plan view of the handle with tool aftixed;

Fig. 2 is an elevational view;

Fig. 3 is a vertical section on line 33, Fig. l;

Fig. 4 is a vertical section on line 4 4, Fig. 3

Figs. 5 and 6 are elevational views of tools diierent from that shown inFigs. 2 and 3, but fitting the handle;

Fig. 7 is a vertical section showing a modification of the handle;

Fig. 8 is an elevational view showing a modification illustrated in Fig.7; and

Fig. 9 is a vertical section showing a further modication.

The tool handle is of T-form having a staff I and arms 2 and 3 extendingopposite each other at right angles to the staff. The staff has a bore 4therethrough from top to bottom, and the arm 3 has a slot 5 extendingdownwardly from its top and communicating with the bore 4. The bore 4and slot 5 accommodate a tool 6 which has a stem extending through thebore and a shank 'l resting in the slot. The shank is at right angles tothe stem and connected thereto by a bend or elbow 8.

The arm 2 has a set screw 9 threaded therein and positioned to engagethe perimeter of the bend or elbow 8 on the tool, in such a manner as tohold the tool against displacement.

By reference to Fig. 3 it will be seen that upon backing out the setscrew 9, the tool 6 will be disengaged, and may be removed upwardlythrough the stem.

It may be understood that the handle 3 will accommodate a tool such as ahollow screw wrench shown in Fig. 3; a screw driver 65 shown in Fig. 5;or a bit 66 shown in Fig. 6; all of which are merely illustrative of alarge variety of tools which may be used.

The tools may have a cross section circular or polygonal in form, or ofother cross section if desired.

The handle may also be of metal, wood, plastic or the like. Fig. 7 showsa modification in which the handle is made of plastic with a metal lineror bushing l0 molded therein, the bushing being threaded to accommodatea set screw.

A ferrule Il may be attached to the lower end of the stern by a bayonetjoint, as specially shown. It has a bore coaxial with the bore 4 but ofreduced diameter, so as to adapt handle to tools of lesser diameter thanthose for which the handle is otherwise adapted.

Fig. 8 shows a modification in which a diierent type of set screw l2 isprovided. This set screw has an enlarged head i3 with a hexagonal socketI4 which will fit the shank end of any one of a number of tools such as6 and 65, made of hexagonal bar stock. Thus the set screw can bemanipulated by any one of several tools in the set.

It will be obvious that various changes may be made in the details ofconstruction, within the scope of the appended claim, without departingfrom the spirit of this invention, parts of the invention may be usedwithout the whole, and improvements may be added thereto while retainingthe full benefit of the invention.

I claim:

A tool handle having a stai and an arm eX- tending at right angle to thestair, the staff having a bore therethrough and the arm having a slotextending downwardly from its top and communicating with the bore, thebore and slot being adapted to accommodate a tool having a stemextending through the bore and a shank, connected at right angles to thestem by a bend or elbow, seated in the slot, and a set screw threaded inthe handle and positioned to engage the perimeter of the bend on thetool in such a manner as to hold the tool against dis placement.
